a year ago one of my tires wore out pretty bad and i went to discount tire to replace it. i purchases a pair. These pair of tires came with a warranty on them including 2 free patches and 2 free tire replacement if lets say one goes flat. Well yesterday one of my tires went flat from a nail. my car is dropped. I went to discount tire today and told me that they won't replace the tire for free because my car was dropped. And i ask them "even though the real problem my tire is flat is because this nail?" And they said yea. they added that the inner wear of the tire cause by the negative camber is the problem. So am i being scammed or they telling me the truth?
